Coffeemaker Redesign

Proctor-Silex, Simply Coffee

Redesign by:

Konstantinos Boukouris

Bradford Lamiman

Edward Moradian

Adam Ouimet

Winter 2004

The coffeemaker was redesigned to create a high quality, cost efficient product. The number of parts was greatly reduced, by using snap fits that replace screws and compliant mechanisms to replace springs. This reduction in parts helped increase the assembly design efficiency which reduces assembly time and in turn the assembly cost, as well as helped reduce the cost of the components.  The materials were chosen to be stronger and cheaper than the current materials, which will increase the quality of the coffee maker overall, as well as reduce it’s price even further. This redesign was developed by Konstantinos Boukouris, Bradford Lamiman, Edward Moradian, and Adam Ouimet in Winter 2004, instructors: Prof. Sridhar Kota, Mentor Dr. Donald Malen, and Teaching Assistant Kerr-Jia Lu.
